Eye muscle movement quantitative detection device

Abstract

The invention discloses an eye muscle movement quantitative detection device, which comprises a housing and a liner which is arranged in the housing, wherein guiding mechanisms for guiding eyes to gaze at different positions are arranged in the liner; a camera, which is used for acquiring eye images, is additionally arranged in the housing; and an observing window is arranged on the outer surfaceof the housing. According to the quantitative detection device provided by the invention, an angle of strabismus and muscle force conditions of six eye muscles are recorded in a mode of images, so that solid-state image data can be provided for manual measurement or analysis by virtue of computer software, and subsequently, the reliability and repeatability of an examination result can be greatlyenhanced.

Description

technical field [0001] The invention relates to the technical field of eye detection, in particular to an eye muscle movement quantitative detection device. Background technique [0002] Strabismus is one of the common eye diseases in ophthalmology, accounting for about 5% of the general population. Among them, the quantitative evaluation of strabismus angle and ocular motor function is the main important content of strabismus diagnosis and preoperative examination. At present, commonly used measurement methods include synoptic machine inspection, visual field arc inspection, and prism inspection. [0003] For the quantitative detection of eye muscle movement, the attending doctor uses gestures to guide the patient's eyeballs to gaze in nine diagnostic directions, so as to roughly quantify the eyeball movement function. Judgment results are greatly affected by subjective factors. Due to the different proficiency or experience of different doctors, there may be great devia...

Problems solved by technology

Due to the different proficiency or experience of different doctors, there may be great deviations in the examination results of the same strabismus patient, which is not conducive to objectively reflecting the disease and scientifically formulating treatment plans, and is also not conducive to the pre-operation, post-operation and long-term follow-up. objective observation

At the same time, it also seriously restricts the development of strabismus diagnosis and treatment in grassroots hospitals.

[0004] In terms of strabismus angle inspection, although the prism + cover method is widely used and recognized at home and abroad, different measurers also rely on manual operation and subjective eye observation to judge, and the results are also quite different. Skilled inspection skills and expertise

However, the main function of the synoptic machine examination is to analyze the binocular single vision function. The angle of strabismus detected by the test is not stable and the reliability is not high. Therefore, clinically, surgery will not be designed according to the degree of strabismus checked by the synoptic machine.

Visual field arc inspection is a reliable nine-direction oblique angle inspection method that is still recognized so far. It is based on the position of the reflective point of the corneal flashlight, and the degree of strabismus is judged after manual inspection. Although it is relatively convenient and quick, it is comprehensive (less than 5m, etc. Azimuth gaze check function), accuracy and repeatability are poor, and it is not suitable for data transmission and sharing in the Internet era

At present, there is no intelligent image inspection-analysis instrument for strabismus at home and abroad
